` Toon B0B BORING` HUBS` To RECEIVE Boxns.

' `Specification bf Letters Patenti No. 12,598, dated March 27, 1855.

Be it known that I, URIAs KIMBLB, of Penfield,in the countyI of Monroe and State of N ew York, have invented aTool to Cut the y Gain in Wagon-Wheels for Setting the Box, .y which I call a Box-Setter; and I do herep by declare thatthe following is a full and exact description ofthe construction and `operation of the same,"reference` being had to the annexed drawings, making a part of Figure 1 1s a perspective view of the shaft.

` `Fig. 2 isa perspective view of theha-ndle. Fig. 3 isa perspective view of the slide gage.

Fig. 4t is a perspective view of the adjustable knife.` Fig. 5 is a perspectiveviewof the `oval shaped box and nutresting on the top The nature of my `invention consists in `constructing a shaft about eighteen inches j long. `"About onethirdqoftheupper end of j this shaft is square.` "l The remainingpart I `make round and cut a screw on iton which I run a nut with spurs on'rthe bottom of the nut which rests on an oval `shaped box "which has ahole` through it to receive the shaft. I attach an" adjustable `gage to the shaft `which `is .kept` in its `place by a set screw. I alsofat-tach an adjustable knifeto the shaft` which is held in its place by a set f Vscrew. There isa handleto the top of th shafttoturnitlby.`

j `'Io enable others" to make and use my invention I will `proceed to describe its construction andoperation.'

` I construct a shaft (Ffg. 8) from eighteen {totwenty inches longand` about one and a "fourth inches square atjthe top with about two thirds of the bottom part round. I j x make the shaft of` iron 0r any `othersuitable material.`

j. on'i the upper end of the shaft to turnit by. .I cut a screw on the round part of the shaft I attach a handle (Fig. 2)

and fit a nut (Fig. 5) to it with spurs on the underside of it` to hold it from turning the `spurs catching to the, box it rests on. I

Iconstruct an oval-shaped box (Fig. 5) about- "lve inches long with a hole in the center to `receive the round part of the shaft.

This box l. p. issquared at each end and of the right size to fit in the hub of the wheel when rimmed ibut ready` to set the box. The screw `with spurs on the underside is to be run on to the shaft and the oval shaped box is to follow it. I construct a gage in shape like an L (Fig. 3) with a slot in it for a set screw to hold itto the shaft above the knife. I construct a knife or cutter (Fig. 4) of steel the shank to the knife is about half an inch square and one and three fourths inches long or as long as may be necessary. The

lknife is formed on the end of the shaft in,

shape like the set to an auger the square `part of the shank to this knife runs through the square part of the shaft just above where it is round and is held in the place defined by a set screw.

The object of this invention is to cut a gain inthe hubs of wagon wheels of any desired size and depth and to cut the gain in the center of the hub by a quick and easy mode insuring uniformity combined with `facility and economy and is so constructed that by the use of the gage (Fig. 3) that it cuts the gain the depth desired. The knife (Fig. 4) may be set to cut any sized gain desired. The oval shaped box (Fig. 5) through which the shaft runs is calculated to steady'the shaft and may be adjusted as it is oval so that the knife will start in the center whether the hub is rimmed out true or not previous to cutting the gain it is to be driven intoI the hub sufficiently tight to steady the shaft when in motion. rl`he nut (Fig. 5) is to prevent the knife from going in or cutting too fast. The spurs on the bottom of the nut is to prevent its turning when the shaft is in motion. The handle (Fig. 2) is to turn the shaft which gives the knife its motion while the knife is cutting the gain to receive the box to be set.

I do notclaim the shaft, the adjustable knife, or the adjustable gage as they have been known before, but

I claim- Y The oval shaped box with the nut with spurs on the under side resting on the oval shaped box in combination `with the shaft the knife and the gage for the purpose
